At this time, Wikidata is not much better. It knows about the laureates there is an article for. A few additional facts have been added but that is about it. The information is available in the most relevant languages..

When an organisation like the AAAS so chooses, they can add additional data. Data about the laureates, when the award was conferred to them and they may even add people missing in Wikidata. or they may find that Kyoshi Kurokawa is the 2012 laureate . The benefits to the AAAS will grown in time. Japanese people may learn about the AAAS, Wikidata will become more relevant as a hub for Open Data and consequently people will become even more exposed to the AAAS.

Obviously, this invitation is open to all organisations that confer awards. It is open to people who care about such things.
Thanks,
